Update Google Place API

exports.places has been updated with pagetoken args which is necessary
to get subsequent places as the initial request returns 20, pagetoken
must be passed to get additional places from a location.

Also updated the URI to the new Google places URI as documented here
https://developers.google.com/places/documentation/search, the lat/lon
arguments were also failing on the stringily command which was
converting the +, into ascii hex codes and passed to the created URI
